Fierce and ruthless, Evil/mocking smile and taunting vibe, Cynical and nihilistic,  God-like and authoritative, Dark-side mirror, She's not purely evil (she protects Kyuusyou), but she's the ominous, despair-inducing side that contrasts sharply with the main girl's chuunibyou heroism and creativity. Ominous, powerful, apocalyptic queen — like a darker, villainous mirror of Kyuusyou turned into a god of misfortune. (In lore she has no "real" face/form). Would be genuinely surprised if not feared.
